Might be, or not (could be a NIC bug)Dunno why sendfile sits in the layer of NIC and how they interact.sendfile() relies heavily on TSO capabilities, a buggy NIC could corrupt frame content on some obscure occasions. We had some known cases on IPv6 for example.
Similarly I remind having experienced bugs on early Yukon chips years ago that would regularly emit total crap on the wire. Willy
